CROSS-REFERENCE TO RELATED APPLICATION [0001]This application is a continuation-in-part of application Ser. No. 11/377,975 filed on Mar. 16, 2006, which is incorporated herein by reference in its entirety for all purposes. FIELD OF THE INVENTION [0002]The embodiments of the present invention relate to a mobile device for cleaning road and street surfaces, more particularly, the embodiments relate to a mobile, all water configuration, street sweeper and cleaning system and method of using the same. BACKGROUND [0003]Vehicles configured with street or road cleaning systems are well-known in the prior art. The systems commonly utilize combinations of brushes and water to collect debris and clean a subject road surface. Unfortunately, the prior art systems suffer from drawbacks, including inefficient operation, large water consumption, complex configurations and ineffective results. Often times the prior art systems simply use brushes which tend to move debris from one location to another without collecting the debris and leave large, hazardous pools of water. Additionally, the current systems cause dust to be disseminated throughout a wide area surrounding the cleaning system. [0004]Even though the current street sweeper systems suffer from the aforementioned drawbacks, there is a tremendous need for such sweepers. Accidental and intentional litter, dust from construction projects, landscape remnants and similar debris commonly finds its way onto roads or streets. When on streets, these materials are unsightly and can create a hazard for drivers. In addition, construction sites and the like must abide by environmental regulations requiring a clean work site. [0005]Thus, there is a need for a street sweeper that overcomes the drawbacks of the prior-art street sweepers. SUMMARY [0006]Accordingly, a first embodiment of the present invention discloses a surface cleaning system comprising: a storage system; a collection ring coupled to the storage system via a debris conduit extending generally from the collection ring to the storage system; and a water pump operable to draw water from the storage system and discharge the water through one or more spray nozzles adjacent to, and directed into, the collection ring wherein the discharged water forces debris and water into the collection ring. The surface cleaning system further includes a collection tray positioned within the collection ring and extending to an opening of the debris conduit and a trash pump positioned within the debris conduit for forcing debris and water from the collection ring and collection tray into the debris conduit. [0007]In a second embodiment, the surface cleaning system further includes one or more spray nozzles and/or air spray nozzles positioned along a length of the debris conduit for forcing debris and water through the debris conduit and into the storage system and a clarifier tank having a mesh screen positioned within the storage system for separating debris from water to produce substantially clean water. [0008]A third embodiment of the present invention discloses a method of cleaning a road or street surface comprising: projecting water against a road surface such that debris is collected into a collection ring; forcing debris and water from the collection ring along a debris conduit using a trash pump; and collecting debris and water from the debris conduit into a storage container. The method further includes directing debris, water and other heavy particles into the collection ring using one or more adjustable screens adjacent the collection ring and separating debris from water using a clarifier tank having a mesh screen to produce substantially clean water. [0009]The street sweeper system of the present invention utilizes high velocity water or air streams to collect and, in some embodiments transport, debris to a storage container or tank. Other embodiments utilize an auger to transport debris to a storage container. In one embodiment, the tank includes two compartments into which the debris and water is collected. As described in more detail below, the compartments are each partially open to one another allowing water and debris to separate and collect into respective compartments. [0010]Other variations, embodiments and features of the present invention will become evident from the following detailed description, drawings and claims.
